For the Zenith colors IIRC they are all the same.
Probably the same on other brands too.
Symptoms are if opened pulsating pix. Shorted

The capacitor used with a CV transformer forms a resonant circuit with the winding driving it. The value is critical to proper operation, so I would really suggest finding a 3.5 uF if at all possible.
